Abstract
The method is used for determining a characteristic value for the binding force potential of paper fibers present in a fibrous suspension prepared for paper manufacture. According to the invention, the air content of the fibrous suspension is measured and this characteristic value derived therefrom. The correlation between the characteristic value and the air content ascertained can be discovered, e.g. by means of series of empirical measurements. With the aid of this method, e.g., the runnability on the paper machine can be assessed and corrected before breakdowns occur.
